WASHINGTON (CNN) - Democratic Sen. Mary Landrieu of Louisiana said Saturday she has decided to support a floor debate on the Senate's health care reform bill.
But she added a caveat on the floor of the Senate: "My vote today to move forward on this important debate should in no way be construed by the supporters of this current framework as an indication of how I might vote as this debate comes to an end.

"It is a vote to move forward to continue the good and essential and important and imperative work that is under way."
Sixty votes are needed to move the controversial bill to the floor for discussion. The legislative body is expected to vote Saturday night. The only senator who has not publicly announced how she will vote on the debate question is Blanche Lincoln of Arkansas.
